Adding example CDL file swath_AMSU_Brightness_Temp.cdl #29
Conversation

i have updated the testing of these CDL files, and fixed an associated test failure. Each file creates its own test case now. I have merged a number of CDL files However, for this file, the test is failing, see: the ncgen command is failing. please could you have a look locally and try to ncgen this CDL file and see if there is a simple mistake in the syntax which would fix this? thank you |

@marqh I found the problem. It was the _FillValue attribute on the string time variable. Thoroughly non-standard, and although the CDL was generated from an actual file, ncgen refused to accept it. I don't know if I am free to click the "Merge pull request" button. Would you rather? |

thank you @JimBiardCics i'll hit merge |
This file describes a set of swath observations. In this case the swath is acquired as a satellite instrument acquires measurements by scanning across the surface of the earth perpendicular to the direction of satellite motion. The independent dimensions in this instance are scan number and pixel in scan. These are not represented as true coordinate variables in this file, but this is not always the case. The result of the observations is a 2D image for each measurement quantity acquired, but this image does not lie cleanly on a lat/lon or projected x/y coordinate grid, so the geospatial coordinate variables are also 2D. There are a number of quality flag variables that provide information about the measurements.
